Efficiency of dye-sensitized solar cells [DSSCs] was enhanced by combining the use of TiO2 nanotubes [TNTs] and nanoparticles. TNTs were fabricated by a sol-gel method, and TiO2 powders were produced through an alkali hydrothermal transformation. DSSCs were constructed using TNTs and TiO2 nanoparticles at various weight percentages. TNTs and TiO2 nanoparticles were coated onto FTO glass by the screen printing method. The DSSCs were fabricated using ruthenium(II) (N-719) and electrolyte (I3/I3-) dyes. The crystalline structure and morphology were characterized by X-ray diffraction and using a scanning electron microscope. The absorption spectra were measured using an UV-Vis spectrometer. The incident photocurrent conversion efficiency was measured using a solar simulator (100 mW/cm2). The DSSCs based on TNT/TiO2 nanoparticle hybrids showed better photovoltaic performance than cells made purely of TiO2 nanoparticles.
通过结合使用二氧化钛纳米管（TNTs）和纳米颗粒，提高了染料敏化太阳能电池（DSSCs）的效率。TNTs通过溶胶 - 凝胶法制备，二氧化钛粉末通过碱水热转化法生产。使用不同重量百分比的TNTs和二氧化钛纳米颗粒构建DSSCs。通过丝网印刷法将TNTs和二氧化钛纳米颗粒涂覆在FTO玻璃上。使用钌（II）（N - 719）和电解质（I3/I3-）染料制备DSSCs。通过X射线衍射和扫描电子显微镜对晶体结构和形态进行表征。使用紫外 - 可见光谱仪测量吸收光谱。使用太阳模拟器（100 mW/cm2）测量入射光电流转换效率。基于TNT/二氧化钛纳米颗粒混合物的DSSCs表现出比纯二氧化钛纳米颗粒制成的电池更好的光伏性能。
